I'm sorry to say, but much like the previous Mi A2 (and A1), there will *never* be a stable upgrade (only slightly less buggy versions, *if* you are lucky). Xiaomi massively sucks at fxing issues, and you can start by the fact they never actually acknowledge there is an issue! Whenever they f$%& up the standard operating procedure is to remove the update from the server and then pretend it never existed. Got a bricked phone? Sucks to be you, good luck explaining the repair center it wasn't your fault.

The stone cold truth about their Android One program is that it is a sham! You pay a premium for the Android One vs. the *exact* same phone with MIUI, but you get even worst support than the cheaper version. They want you to buy MIUI so that they can sell ads on your phone, and gather data about you to generate more revenue.
